This paper provides evidence based on French macroeconomic data, that shocks on the cost of oil inputs are transmitted asymmetrically to the prices of fuel. We use an error correction model to estimate the dynamics of the transmission of the cost of crude oil expressed in French currency, to the...

Statistical tests in vector autoregressive (VAR) models are typically based on large-sample approximations, involving the use of asymptotic distributions or bootstrap techniques. After documenting that such methods can be very misleading even with fairly large samples, especially when the number...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

We estimate the reaction function of monetary policy in the Euro area and derive the Taylor-type policy rule that a would-be ECB would have followed since the beginning of the European Monetary System (1979-2003). We first follow the standard GMM methodology developed by Clarida, Galí and...
